Unify is excited to be exclusively partnering with a fast-growing and disruptive SaaS startup entering an ambitious phase of product development. We're helping them build their in-house development team from the ground up.

They are now looking for a Junior Unity Developer to join their creative and technically sharp product team. This is a fantastic opportunity for early-career developers with a passion for interactive 3D applications and strong foundations in Unity and C# development.

About the Company:

This is an early-stage startup with a bold vision: to create a cutting-edge SaaS platform powered by real-time 3D and immersive experiences. They thrive in a fast-paced, collaborative environment and are looking for hands-on team members ready to grow with the business.

Role Overview:

As a Junior Unity Developer, you will help lay the groundwork for the company’s flagship 3D SaaS product. You'll work closely with cross-functional teams including product, design, and backend development to deliver intuitive, performant user experiences using Unity.

You’ll be part of a collaborative and forward-thinking environment where your ideas and code will make a direct impact.

Key Responsibilities:

Build interactive 3D features using Unity and C#, with a strong focus on performance and usability.

Collaborate with backend developers (Node.js / TypeScript) to integrate APIs and data-driven content into the Unity application.

*

Prototype and iterate quickly to meet changing product requirements.

*

Debug, test, and optimise application performance across devices.

*

Contribute to design discussions and technical planning with the wider team.

*

Document code and development processes for maintainability and future onboarding.

Skills & Experience:

Required:

*

1+ year experience using Unity and C# (commercial, freelance, academic, or personal projects).

*

A good understanding of 3D development principles (game objects, animations, asset pipelines, prefabs, lighting, etc.).

*

Exposure to REST APIs or backend integration.

*

Strong communication skills – able to explain technical concepts to non-technical stakeholders.

*

Willingness to learn and grow in a fast-moving startup environment.

Desirable:

*

Experience with shaders, physics, or real-time rendering.

*

Familiarity with Node.js, TypeScript, or SQL is a plus.

Knowledge of version control (e.g., Git).

*

Previous exposure to SaaS or startup environments.

*

UK driving licence (occasional site visits).

What’s on Offer:

*

Career Growth: Be part of something from the beginning – as the product grows, so do your responsibilities and career path.

*

Supportive Team: Work in a collaborative environment where learning and development are a priority.

*

Flexible Working: Office-based in Caerphilly with hybrid working (after 6 months).

*

Annual Leave: Competitive package with room to grow as the company matures.
